This extraordinary collection, which amounts to more than several hundred million lines of code, gives its possessor the entire hacking capacity of the CIA." Chunks of the documents, including the code for the hacking tools themselves as well as names and identifying information, have been redacted.
Nonetheless, Wikileaks claims that the contents of Vault 7 were "circulated among former U.S. government hackers and contractors in an unauthorized manner, one of whom has provided WikiLeaks with portions of the archive."
